In a specific embodiment, the intelligent train communication system comprises a master vehicle-mounted Mesh component 20 arranged on a master vehicle and connected with a master vehicle-mounted host 10 of the master vehicle and a slave vehicle-mounted Mesh component 40 arranged on a slave vehicle and a slave vehicle-mounted host 30 of the slave vehicle, wherein the master vehicle-mounted Mesh component 20, the slave vehicle-mounted Mesh component 40, the master vehicle-mounted host 10 and the slave vehicle-mounted host 30 are automatically wirelessly networked.
Through setting up main vehicle-mounted Mesh part 20, from on-vehicle Mesh part 40, with main vehicle-mounted host computer 10, from the automatic wireless network deployment of on-vehicle host computer 30, with wireless form access vehicle-mounted network, the line of laying of mobile unit need not to be considered in the design of train earlier stage, practice thrift a large amount of manpowers, the time cost, the installation additional of follow-up mobile unit, withdraw from and have very big convenience, vehicle-mounted terminal equipment only need simple configuration can access vehicle-mounted network and form self-organized network, can carry out installing additional of mobile unit wantonly according to the demand of synthesizing decision-making platform, thereby promote the ability that intelligent train system obtained information, whole system is more intelligent.
Because the problem that interference exists between the intelligent train wireless networking and a Wi-Fi network used by passengers possibly exists, the deployment position and the signal strength of the vehicle-mounted Mesh node equipment need to be limited in the application.
To solve the problem that the train side top door is generally made of metal and has strong interference to wireless signals, in one embodiment of the present application, the master vehicle Mesh component 20 is arranged at the position of the inner top passage of the master vehicle, and the slave vehicle Mesh component 40 is arranged at the position of the inner top passage of the slave vehicle
The vehicle-mounted Mesh node equipment of the intelligent train is deployed in the side top channel, the transmitting power of the wireless signals is adjusted, the wireless signals in the side top channel are limited in the channel, and the signals received from the vehicle-mounted wireless network in the intelligent train compartment are weak. Meanwhile, the vehicle-mounted equipment antenna supporting the Mesh network is arranged in the side top channel, and the process that the intelligent vehicle-mounted equipment is accessed into the intelligent train vehicle-mounted wireless network is carried out in the side top channel.
In addition, the vehicle-mounted Mesh node equipment can be also configured with a VLAN function, a wireless network formed by the vehicle-mounted terminal equipment is divided into different VLAN numbers, and the VLAN numbers are isolated from a Wi-Fi network providing service for passengers at a switch, so that the mutual isolation of the wireless network used by the vehicle-mounted equipment and the wireless network serving the passengers is ensured, and the safety of a train network is ensured. By means of isolation of unknown equipment addresses and hiding of SSIDs, a Mesh network formed among the vehicle-mounted equipment is hidden, and passengers are prevented from mistakenly searching and accessing the vehicle-mounted wireless network.
